Useful Automation Patterns
| Workflow | Trigger → controlled result |
|---|---|
| Lead qualification and routing | Form submission → validate, enrich approved fields, score against rules, create CRM record and notify the correct owner. |
| Client onboarding | Paid order → create tasks, request inputs, generate workspace and report missing steps without exposing credentials. |
| Operational reporting | Scheduled run → fetch source metrics, normalise definitions, flag gaps and deliver a dated report with source links. |
| Support triage | New request → classify, attach customer context, suggest priority and leave sensitive or uncertain decisions to staff. |
| Content operations | Approved brief → draft channel variants, send for review, schedule accepted content and record the published URL. |
| Account health monitoring | API or schedule → check status, alert on token expiry or repeated failure and open a reconnect task. |
Workflow Design Checklist
- Name the business outcome. Record who benefits, how often the work occurs and the current cost of delay or error.
- Draw the data boundary. Identify each source, destination, credential owner, retention requirement and prohibited field.
- Define the trigger contract. State required fields, accepted duplicates and what makes an event eligible.
- Make actions idempotent. Replaying a workflow should not create duplicate invoices, messages or records.
- Add validation and branches. Reject malformed inputs and route uncertain cases to a named human owner.
- Design failure recovery. Log useful context, alert after meaningful thresholds and support controlled retries.
- Test with representative data. Include empty, duplicate, delayed, unauthorised and downstream-error cases.
- Assign production ownership. Document monitoring, credential rotation, change approval and how to pause the workflow.
Where AI Fits—and Where It Should Stop
AI is useful for classification, extraction, summarisation and drafting when the output is validated before a consequential action. It should not independently approve payments, delete records, disclose sensitive data or send high-impact external communication without controls appropriate to the risk.
A successful test run is not production readiness.
Production work needs credentials, data handling, duplicate protection, timeouts, rate limits, monitoring, alerts and a recovery path.
Automation Failure Patterns
- Automating a process whose owner and decision rules are still unclear.
- Embedding credentials in workflow fields or logs.
- Assuming every webhook arrives exactly once and in order.
- Retrying a consequential action without idempotency.
- Sending AI-generated text externally without a defined review threshold.
- Building no manual route for provider outages or expired access.
